Tim Cook publicly commemorates the 63rd birthday of Steve Jobs with a Tweet

Apple CEO Tim Cook used Twitter to celebrate Steve Jobs' birthday, using one of the founder's own quotes.

The Tweet by Cook was simple, and was only the latest in a series of commemorations of Jobs' life in the last year by the CEO and by Apple itself.

Remembering Steve, our friend and leader, on his 63rd birthday: "The thing that bound us together at Apple was the ability to make things that were going to change the world." We are forever bound to that goal — and to you, Steve. pic.twitter.com/rDvzR8s2F8

Apple started a year-long series of Jobs remembrances on Feb. 22, 2017 by naming the theater on the Apple Park headquarters facility the "Steve Jobs Theater." Cook name-dropped Jobs throughout the year on assorted interviews.

When the Steve Jobs Theater opened for the iPhone 8 and iPhone X event, Cook led the presentation with a short video celebrating Jobs.
